Have you ever gotten that notification from Uber when you land at a major airport that encourages you to open the app to book a ride and wonder how they figured out your location? The first time I saw this I wondered who betrayed me and shared this data with them.
It turns out that it might be nobody. iOS can publish notifications for an app based on a geographic region and that app doesn’t know the wiser unless and until you interact with it.
I figured that if I didn’t know this, some of y’all might not. https://developer.apple.com/documentation/usernotifications/unlocationnotificationtrigger
